CHECKING THE BATTERY
NOTE:
Since the MF battery is a sealed type battery, it
is not possible to measure the specific gravity
of the electrolyte in order to check the charge
state of the battery. Therefore the charge of
the battery has to be checked by measuring
the voltage at the battery terminals.
CAUTION:
CHARGING METHOD
This is a sealed type battery. Never
●
remove the sealing caps. If the sealing
caps have been removed, the balance will
not be maintained and battery perfor-
mance will deteriorate.
Charging time, charging current and
●
charging voltage for the MF battery are
different from those of general type bat-
teries. The MF battery should be charged
as explained in "CHARGING METHOD". If
the battery is overcharged, the electrolyte
level will drop considerably. Therefore,
take special care when charging the bat-
tery.
WARNING
Battery electrolyte is dangerous; it con-
tains sulfuric acid which is poisonous and
highly caustic.
Always follow these preventive measures:
Avoid bodily contact with electrolyte as it
●
can cause severe burns or permanent eye
injury.
Wear protective eye gear when handling
●
or working near batteries.
Antidote (EXTERNAL):
SKIN - Wash with water.
●
EYES - Flush with water for 15 minutes
●
and get immediate medical attention.
Antidote (INTERNAL):
Drink large quantities of water or milk fol-
●
lowed with milk of magnesia, beaten egg
or vegetable oil. Get immediate medical
attention.
